Safety razor and blade combination



SAFETY RAZOR AND BLADE COMBINATION Filed Sept. 30, 1931 cap of the razor, there being no limitation in this respect.

Another object is to provide a blade having novel positioning means thereon adapted to cooperate with means on a holder.

A specific object is to provide a blade formed with novel positioning means of a flexible nature and which may, before tempering of the blade, be caused to project slightly beyond opposite sides of the opposite ends so as to prevent the blade from lying flat upon a supporting surface, this means not interfering, however, with flat packaging of the blades.

To the attainment of the foregoing and other objects and advantages, the invention preferably consists in the details of construction and the arrangement and combination of parts to be hereinafter more fully described and claimed, and

illustrated in the accompanying drawingI in which:

Figure 10 is a fragmentary plan ViewA of the razor body and blade thereon and disclosing another variation,

Figure 11 is a cross section on the line II-II of Figure 10.

Referring more particularly to the drawing and especially Figures 1 to 4, I have shown a razor comprising a body I5 having guards I8 at its longitudinal edges and a convex seat for a blade I1 of the thin, flexible and usually double edged type. Coacting with the blade is a cap I8 having a screw connection with a handle i9 swivelly connected with the body. While it is immaterial which screw member is carried by the body and which is carried by the cap I have in the present instance illustrated the cap as carrying the male screw received within a threaded socket 2I in the handle. These elements are conceivably reversible.

The blade i1 is formed with two oppositely extending tongues 22 normally lying in the same plane as the blade and capable of being flexed to project beyond one face thereof `so as to be received within recesses 23 in the convex face of the body, these recesses being preferably of elongated rectangular shape with their outer ends defining shoulders 24 and with their inner portions curved and merging gradually into the convex face or blade seat. The ends of the blade are preferably formed with extensions 25 which project beyond the body and the cap to facilitate handling.

In addition to the male screw 2D the cap carries studs preferably integral therewith having frusto-conical or tapered base portions 26 and cylindrical end portions 21, the latter being adapted to fit within circular holes 28 in the tongues 22 and to be received within holes 29 in the body communicating with the recesses 23. At its center the blade is formed with a circular hole 30 of sufficient diameter to pass the male screw 20. The threaded stud or screw 20 is not of uniform diameter throughout but preferably has a constricted neck portion 3| adjacent its juncture with the cap so that in itself it cannot serve to position the blade.

In the use of this form of the combination, the blade may be initially laid upon the convex seat afforded by the body I5 with the holes 28 in thc tongues registering substantially withrthe holes 21 in the body and with the central hole 30 registering substantially with the threaded socket 2l. Instead of this, the cap I 8 may be inverted and the blade I1 laid upon it with the holes 28 engaging upon the ends 21 of the studs carried by the cap and with the hole 30 at the center of the blade engaging upon the threaded stud or screw 20. Regardless of which method is resorted to, it is clear that there will be an initial positioning `of the blade with respect to either the body or the cap. The cap and body members are then moved relatively to start the threaded stud or screw 20 into the socket 2 I, whereupon the handle I9 is rotated with respect to the body and cap for drawing the cap toward the body into clamping relation to the blade. As this is done the Truste-conical or tapered base portions of the studs on the cap engage against the edges of the openings 28 in the tongues and flex the tongues out of the plane of the blade so that they will enter the recesses 23 provided for their accommodation. If the blade be initially laid upon the body without the holes registering exactly properly with the holes 2." it is clear that the tapering of the bases 26 will act to shift the blade to a certain extent for bringing about proper registration so that the blade will be positively and accurately positioned with respect to both the body and the cap.

As a slight modification, I may resort to the construction shown in Figure 5 which discloses the same arrangement as Figures 1 to 4 except that the terminal portions of the studs 32 carried by the cap 33, corresponding to the cap I8, are formed with peripheral grooves C14 so as to make it still more impossible to use a blade not specically designed for use with the razor though these studs will provide preliminary positioning means.

In Figures 6 to 9 inclusive I have illustrated a modification of the invention in which the positioning studs are carried by the body instead of by the cap. Referring to these figures in detail, the numeral 35 designates the body having a convex blade seat and guards 36 at its longitudinal edges. Swivelled at the center of this body is a handle 31 formed with a threaded socket 33 to receive a threaded stud or screw 39 carried by the cap, this screw having a reduced neck 40 at its juncture with the cap. Moreover the body is formed with recesses 4I somewhat similar to the recesses 23 in the first described form and having their outer ends dening shoulders 42 corresponding to the shoulders 24 and having their inner ends inclined or curved and merging into the convex blade seat. However, in this instance the recesses 4I dier from the recesses 23 in the particular that at their outer ends they communicate with grooves 43 having flaring or gles to each other the deflection of the tongue from the plane of the blade produces little or no stilening effect interfering with flexing of the blade. l

In all forms of the invention it will be observed that I have made adequate provision for preliminary positioning of the blade and also for positive securing of the blade in final accurately positioned relation with respect to the body and cap. Obviously a blade of ordinary type such as one unprovided with the tongues could not be used as when the main parts are brought together into clamping relation to the blade the blade, being brittle, would become broken. Another consideration is that all of the parts, that is to say the body, cap, studs, blade and details of the latter cooperate in every respect so that the holder or razor proper and the blade constitute what may be termed an inseparable entity or combination, each being dependent on the other and incapable of satisfactory employment without its complement.l In this way the use of a blade not specifically intended for my razor is entirely precluded and a manufacturer of the combination may be in a position to monopolize the manufacture and' sale of the approprlate blades, thereby avoiding possibility of his razor falling into disrepute as the result of the employment of improper and unauthorized blades in association therewith.

From the foregoing description and a study of the drawing it is believed that the construction, operation and advantages will be readily apparent to one skilled in the art Without further explanation.

While I have shown and described the preferred embodiments of the invention, it should be understood that the disclosure is merely an exemplication of the priciples involved as the right is reserved to make all such changes in the details of construction as will widen the field of utility and increase the adaptability of the device provided such changes constitute no departure from the spirit of the invention or thescope of the claims hereunto appended.
